Keep your hands cold.

According to research, playing video games where you move around a lot . . . like "Dance Dance Revolution" or Wii Fit . . . ISN'T as good as doing an actual workout.

But if you're currently getting ZERO exercise, it's better than nothing.  And it can help motivate you to START a real workout routine.  Here are three more things you might not think about that can help you get in shape.

#1.)  Keep Your Hands Cold While You're Exercising.  According to one study, it helps with endurance and makes you more comfortable while you're working out.

You don't have to duct tape cold packs to your palms or anything.  Just picking up a bottle of cold water every few minutes can help.

#2.)  Work Out with Someone Who's in Better Shape Than You Are.  In a study from last year, researchers had people ride stationary bikes for as long as they could stand it.

Then they had them do it again later on.  But while they were doing it the second time, they could see video of someone who was in BETTER shape also riding a bike.

And with the extra motivation, the people in the study biked almost twice as long as they had the first time.  So in other words, working out with someone who's in better shape than you are makes you competitive about your workout.  

#3.)  Bring Your Dog to Work with You.  Obviously most people aren't ALLOWED to.  But a recent study found that people who do it tend to get more exercise, because they always go on walks during their lunch breaks.
